Abstract
The thermal (DSC) and electrical (IS) and structural (XRD) behavior of MI-AgI (M = Na, Li) systems were investigated for temperatures above 300 K. The slow evaporation method was used to synthesized samples under concentrations given by the relationship: xAgI-(1-x) NaI and xAgI-(1-x) LiI with x = 0.8. The characterization results reveal how the AgI conductivity jump at T = 420 K, this was reduced when the Li+or Na+was interchanged for Ag+ion due to the cooperative effects of ion-ion and ion-lattice interactions. The transition temperature of the system decreased as the doping concentration was increased. The reached conductivities (>10-4 S/cm) and the low activated energy values (lower than those found with AgI) show the importance of xAgI-(1-x)LiI systems, allowing a wider knowledge of the behavior of solid conductors developed based on silver iodide compounds.
